It is provided that the photovoltaic modules are each provided with two poles for establishing an electrical connection, which electrically link the photovoltaic modules facing west and east facing each other separately. As already explained above, such a separate connection between east and west is necessary in order to counteract a reduced output of the photovoltaic system, since the photovoltaic modules deliver different amounts of electricity depending on their orientation towards the sun.

  • a particular advantage is that an east-west alignment of the individual photovoltaic module is to be implemented due to the module parts arranged relative to one another, the module planes of which together enclose an angle between 0 ° and 180 °. This is due in particular to the fact that when one module part is aligned in a westerly direction, the corresponding other module part is automatically aligned in an easterly direction.

This can be justified by the fact that the number of photovoltaic modules within a module string is increased and thus the number of module strings that are connected to the inverter is reduced. In contrast to the module strings known from the prior art, the number of photovoltaic modules within a module string can preferably be doubled and thus the number of module strings can be halved, so that the connection lines between the module string and the inverter are halved.

  • the inverter should only be an example, since further devices can be connected between a module string and the inverter.
  • the use of an electrical line with a reduced diameter is feasible because the total current intensity which emerges from the module parts oriented in the east and west direction no longer reaches the same current intensity as the photovoltaic modules known from the prior art with one orientation.
